'o all /r/'rm'n/ t nt/rf] colt/:ern: v Be it known that l, DANIEL, M. Pix-wav., aV citizen of the United Sta-tes,rcsiding at Germantown, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful improvements in Crossings for Elevated-Railway Structures with." Suspended (lars, of which the following is a specificationA My invention hasrelation to that class ofA elevated-railway strut-,tures in which cars suspended from such structures are usedand in which two structures intersect cach other at right angles, and in such connection it lates to crossings 'adapted to be arranged in such intersecting elevated-railway structures.

The principal objects of my present invention are, first, to provide a simple and efiicient crossing yfor elevated-railway structures; second,to provide one of the abutting elm'ated-railway structures with doors or wings carrying rails adapted. to form. the continuation of the main line and the crossing for the intersecting line; third, to proj vide said doors or wings with means meshing with each other to control and to transi'hit the movement of one or more of the doors or wings to the other doors and to heidi/the saine iu proper position with respect to each other, and, fourth, to provide a car with a hui'fer adapted to contact with. one set of doors and to automatically shift the doorsor wings into a position so to'perinit of the travel of the car over the mainline or intersecting line. i

The nature and sco e of/h/iy present invention will'he vmore ful y understood from the following description, taken in connection with the accompanyingr drawings, forming part hereof, in which- Figure l illustrates, in side elevation, an automatic crossing of two elevated-railway structures intersecting each other at right angles embodying main features of mylinvention. Fig. 2 is a horizontal sectional. view of said crossing, illustrating inpfull and dotted lines the different positions .of the doors or wings in said crossings. Fig., 3 is a View, partly in elevation and partly in section, illustrating' in for controllingthe movement of the doors or Wings and buffers foraetuating the doors or ting girders Z and l.

wings, said buifers being arranged on the roof of a car and in the path of the saine. Fig; 4 iliustrates. in. side elevation a portiony of a car and the buffer adapted to contact with and to open the doors or wings: and Fig, 5 is a sectional view, enlarged, of the upper portion of the buffer. i

Referring to the drawings, and b, are

7e, and Z and l are girders of the intersectii'ig line abutting against at right angles the girders lr. The girders 7c of the Igirders b of the niain line are provided with a crossing, consistingr of floors or wings 71. and fr. abutting elevated structure has no'doors or l wings, sue-h as are arranged in the main line i') and b', as the doors /i and i thereof forni the crossing for theintersccting line Z and L, ,as shown in dotted Ylines in vFig. 2. The doors or wings h and 'i are pivotally con neeted to bolts or shafts /z and 7i, preferably connected at their upper ends to plates h" and h5, secured to the top ofthe girder k, .and at their lower ends are in engagement with plates lz? and hs of the girder r and abut- As shown in Figs. 2 and 4, each of the doors or wings is provided with two rails m and a, on either side thereof. In the position of the doors fr and it (shown in `full lines in Figs. 1 and 2) the rails m forni the continuation of the rails b* and b9 of the main line, while in the position indicated by dotted lines in Fig. 2 the rails flzf form the continuation of the rails 'n' and of the abutting cross-elevated structures! and l. Each of the doors 7i. and h, at their .upper ends, is provided with a sclnicircular geari wheel o. These gear-wheels mesh with each other and have their fulcral points on the shafts h2 and h3., as shown in Figs. `l and 2.

By this arrangement thev movement of one I and positively controlled by the saine.

` .Tn order to automatically open the doors hand h and to shift the saine from their norlnal position (indicated in full lines in ,I `ig. `2)V into the position indica-ted,` by dotted lines in said figure, a car d, suspended from the elevated-railway structure, is provided with a buffer j), located on the roof d there of, as shown in Fig. 4. The buffer y) consists The of a rod p', provided at one end with a roller girders of the inain Tine, between which` are interposed, prelerably, lattice-work girders door is readily transmitted tothe other door
